Answer 1

lines that will never cross and are the same distance apart and may go on forever (lines will not cross if they go on and on)

Question 2

Arc

Answer 2

Part of a circle that represents an angle between two intersecting lines.

Question 3

Angles

Answer 3

When lines intersect they form angles and angles are the spaces or shapes that are formed between the intersecting lines- they meet at a vertex. Name angles by names of points.

Question 4

Perpendicular

Answer 4

lines that form square corners when they intersect, they form right angles.

Question 5

Right Angles

Answer 5

lines that form it are perpendicular and the angles measure 90 degrees.

Question 6

Intersection

Answer 6

when lines cross they cross at a point called the intersection

Question 7

Acute angles

Answer 7

Angles that are less than a right angle; less than 90 degrees

Question 8

Obtuse angles

Answer 8

angles greater than a right angle: greater than 90 degrees

Question 9

Straight Angle

Answer 9

A straight line-two rays pointing in the opposite directions and it equals 180 degrees

Question 10

Complementary angles

Answer 10

Two angles that form a right angle are called complementary angles =90 degrees

Question 11

Supplementary angles

Answer 11

Two angles combine to form a straight angles=180 degrees

Question 12

Vertex

Answer 12

Point where two rays meet

Question 13
